    • INVERTED PENDULUM WITH LINEAR SYNCHRONOUS MOTOR SWING UP USING BOUNDARY VALUE PROBLEM 

      Autor: Koska , Lukáš; Jadlovská , Slávka; Vošček , Dominik; Jadlovská , Anna
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Research in the field of underactuated systems shows that control algorithms which take the natural dynamics of the system’s underactuated part into account are more energy-efficient than those utilizing fully-actuated ...

    • MODEL-BASED SECURITY ANALYSIS OF FPGA DESIGNS THROUGH REINFORCEMENT LEARNING 

      Autor: Vetter , Michael
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Finding potential security weaknesses in any complex IT system is an important and often challenging task best started in the early stages of the development process. We present a method that transforms this task for FPGA ...

    • STUDY OF SAMPLES STRENGTH OF MATERIAL FORMED BY THE PROCESSES OF COMPACTION EXTRUSION AND TUMBLING GRANULATION 

      Autor: Peciar , Peter; Ružinský , Radovan; Guštafík , Adam; Karľová , Mária; Čierny , Matúš; Fekete , Roman; Peciar , Marián
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      In a period of industrial expansion, protection of the environment is often neglected during the mass manufacture of products. One of the problems of our society that is necessary to face at present is the provision, ...

    • TECHNOLOGY OF PRODUCING REINFORCED CONCRETE COLUMNS OF CIRCULAR CROSS-SECTIONAL AND INVESTIGATION OF THEIR STRAIN-STRESS STATE AT TRANSVERSE-LONGITUDINAL BENDING 

      Autor: Rogovskii L., Ivan; Titova L., Liudmyla; Davydenko O., Oleksii; Trokhaniak I., Viktor; Trokhaniak M., Oleksandra
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The paper presents a method of producing Circular Cross-Section Columns (CCSC), which can provide sufficiently precise dimensions, with longitudinal reinforcement securely fixed in special plugs. An investigation procedure ...

    • THE EFFECT OF SOIL GRAIN SIZE ON THE DEFORMATION PROPERTIES OF REINFORCED GEOCELL LAYERS 

      Autor: Luňáčková , Barbara; Mohyla , Marek; Pinka , Miroslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The effect of backfill material grading on the behaviour of geocell reinforced layers was experimentally investigated in this study. A series of loading tests were performed on a model with geocell reinforced and unreinforced ...

    • TRACK GAUGE STABILITY UNDER EFFECT OF SLEEPER THERMAL EXPANSION 

      Autor: Lojda , Vít; Krejčiříková , Hana
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Railway sleepers are traditionally made of hardwood, pre-stressed concrete or steel. However, emerging advanced materials, including polymers or composites, are investigated for a possible employment in the sleeper production. ...

    • TUNNEL PORTAL INSTABILITY IN LANDSLIDE AREA AND REMEDIAL SOLUTION: A CASE STUDY 

      Autor: Farhadi Ayoublou , Farhad; Taromi , Majid; Eftekhari , Abbas
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      The construction of tunnel portals in mountainous or slope areas often involves problems, which are closely related to factors, such as slope topography, geology, geotechnics, construction geometry and the tunnel excavation ...
